I think 11" tablet is overkill. I use my 7.5" iPad Mini and that is way large enough. When you get up to the larger tablets just seems added weight and size is not worth it, at least for me.
Actually, I found the 11” iPad Pro too dim, even with a Surf to Summit hood on the iPad for use in bright sunlight. If you want to buy a brand new hood, used twice contact me.

It's perfect and fits in the flymore case easily. No idea why you can't find them on amazon. The plastic is thick and the hold is very comfortable. I'm not sure if it'll fit the ipad pro, but it probably will since my ipad fits even with the case on it.
You'll also need a 1ft usb-c cable. Mine uses a lightening and this is what I got (Don't buy this for the ipad pro)
